SYNOPSIS

In the mid-troposphere, a large blocking dipole pressure structure persists over the eastern North Atlantic with a low west of northern Portugal and a high south of Iceland. Flow is weak over much of central and southern Europe. Another low pressure system is present over northern Turkey. A trough over the Barents Sea embedded in a strong westerly flow should sharpen implying a strong northerly jet will develop over the Norwegian Sea and Norway southward.

DISCUSSION

Iberia...

In the range of the low near Portugal, a zone of stratiform precipitation over the NWrn third of the peninsula will be followed by convective showers, many of them thundery. Low instability and weak to moderate wind shear strongly limits the potential for severe convection.
